Steel Spore Disc Biological Indicators

An inoculated carrier, 6 mm steel disc, of Bacillus atrophaeus (Cell Line 9372) with a population level of 103,104, 105 or 106 or Geobacillus stearothermophilus (Cell Line 7953) with a population level of 103, 104, 105 or 106.

These Biological Indicators (BIs) for use in monitoring Vaporized Hydrogen Peroxide (VH2O2) sterilization processes. The BIs are designed for monitoring processes whether placed directly into the chamber, positioned in areas of a device which are the most difficult to sterilize or distributed

  • Convenient shelf packages of 100 units per box
  • Products are accompanied by a Certificate of Analysis and are certified with population, purity, and resistance characteristics (D value, survival and kill where applicable)
  • ISO 11138-1 Compliant

The Spore Discs are utilized to monitor VH2 O2 sterilization process efficacy. The Spore Discs are labeled For Industrial Use Only.

Place Spore Discs (a minimum of 10 per exposure is recommended) inside representative materials to be sterilized. Package or wrap product as usual, if applicable. Locate the test packages or Spore Discs in areas most difficult to sterilize, as outlined in your specific sterilization validation protocol (usually four corners front, four corners rear, center-center and center-top) or according to standard operating procedure. Run the cycle.


  • After sterilization or exposure, remove Spore Discs or product from sterilizer.
  • Aseptically transfer the Spore Discs to Soybean Casein Digest Broth (SCDB).
  • Transfer one Spore Disc which has not been exposed in a sterilization process as a Positive Control.


Incubation: At least one unused tube of culture medium from the same lot should be incubated with the test series as a Negative Control. Place the cultured Spore Discs, the Positive Control and the Negative Control in an incubator set at 55°C to 65°C. Incubate for a minimum of seven days or per a validated reduced incubation period.


Monitoring: Examine the Spore Discs daily during incubation. Record observations.

Testimonial from VP Antibody Manufacturing

“This pump cut our processing time from 3 days to 1 shift. I’m not giving this pump back. You will have to come and get it if you want it... and that won’t likely happen.”
